They are primarily sold in the United Kingdom, the Isle of Man and Ireland but are available in Australia, New Zealand, South Africa and several European and Asian countries (e.g. Taiwan and Hong Kong). In Italy they are now marketed as a variety of digestive biscuit, having previously been known as Suncrok. They were also released in Canada in November 2012, made available in Wal-Mart's British modular section in their food aisles. The McVitie's Hobnob is the third most popular biscuit in the UK to "dunk" into tea, with its chocolate variant sixth.[2] In 2014 a UK survey declared the Chocolate Hobnob the nation's favourite biscuit.[3]

The original tagline of the Hobnobs was "one nibble and you're nobbled",[5] and was removed. It has since been brought back, but slightly changed by adding "hob" to the beginning of the last word.[6] The tagline "Chocolate now has Hobnobs underneath" was used for the introduction in the UK of chocolate Hobnobs.
